A quantum‐secured authentication framework, QSAFE‐V, is introduced for vehicular Tactile Internet environments. By integrating Quantum Identity Tokens, lattice‐based cryptography, and edge‐assisted verification, the framework enables lightweight mutual authentication with strong resistance against replay, impersonation, and quantum‐enabled attacks ...

Twin-field quantum key distribution with passive-decoy state
Twin-Field quantum key distribution (TF-QKD) and its variants, e.g. phase-maching QKD, sending-or-not-sending QKD, and no phase post-selection TFQKD promise high key rates at long distance to beat the rate distance limit without a repeater.

A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

We present an adaptive procedure for aligning quantum non-locality experiments without any knowledge of the two-qudit state shared by the participating parties. The quantum state produced by the source, its unitary evolution as well as the actual measurement bases remain unknown to both parties at all times.

Simulation of a submarine to submarine QKD system
Due to the absorption of water, communication between two parties submersed below the water is normally performed with acoustic waves. However, with the need for higher data rates, the use of RF or optical frequencies is needed.

This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.

Numerical method for finite-size security analysis of quantum key distribution
Quantum key distribution (QKD) enables secure information exchange with untrusted quantum links between remote communication parties. A central task in the studies of QKD protocols is security analysis, which aims at deriving the length of the final key ...

Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation
Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.

High-speed integrated QKD system
Quantum key distribution (QKD) is nowadays a well-established method for generating secret keys at a distance in an information-theoretically secure way, as the secrecy of QKD relies on the laws of quantum physics and not on computational complexity.

Experimental authentication of quantum key distribution with post-quantum cryptography
Quantum key distribution (QKD) can provide information theoretically secure key exchange even in the era of quantum computers. However, QKD requires the classical channel to be authenticated, the current method for which is pre-sharing symmetric keys ...
